So I have found with my 7970 that I can go over 1300Mhz on the core, but only if I lower my memory to under 1800Mhz... So is this due to the card using all available power? I have noticed others on the charts that went over 1300Mhz core but had to lower Mem freq.

Well dang. Now I want to do the voltage hardmod on it, but to dang expensive of a card to do that, although done it before with no problems. Guess I will wait until this card has lost some value before I go and break it.
